Micropower Isolated Flyback Converter with Input Voltage
Range from 6V to 100V
Design Note 509
Zhongming Ye
Introduction
Flyback converters are widely used in isolated DC/DC
applications because of their relative simplicity and
low cost compared to alternative isolated topologies. Even so, designing a traditional flyback is not
easyвЂ”the transformer requires careful design, and
loop compensation is complicated by the well known
right-half plane (RHP) zero and the propagation delay
of the opto-coupler.
Linear TechnologyвЂ™s no-opto flyback converters, such
as the LT В® 3573, LT3574, LT3575, LT3511 and LT3512,
simplify the design of flyback converters by incorporating a primary-side sensing scheme and running the
converter in boundary mode. The LT8300 high voltage
monolithic isolated flyback converter further simplifies
flyback design by integrating a 260mA, 150V DMOS
power switch, an internal compensation network and a
soft-start capacitor. The LT8300 operates with input supply voltages from 6V to 100V and delivers output power
of up to 2W with as few as five external components.
The LT8300 operates in boundary mode and offers low
ripple Burst ModeВ® operation, enabling the design of …

Monolithic No-Opto Isolated Flyback Converter Provides
Versatile Solution
Design Note 525

Introduction
Traditionally, isolated power supplies use an optocoupler in the feedback loop to transfer regulation
information across the isolation barrier. Unfortunately,
an opto-couplerвЂ™s gain characteristic varies widely over
temperature and lifetime, increasing the difficulty of
power supply loop compensation.
Linear TechnologyвЂ™s line of no-opto flyback converters,
such as the LTВ®3573, LT3574, LT3575, LT3511, LT3512
and LT8300, simplify flyback design by incorporating
a primary-side sensing scheme, thereby eliminating
the need for an opto-isolator.
The LT8302 monolithic no-opto flyback converter
has an integrated 65V/3.6A DMOS power switch with
internal loop compensation and soft-start. The LT8302
can operate from an input voltage as low as 2.8V to
42V, and deliver output power up to 18W. It offers
low ripple Burst Mode В® operation at light loads, providing low standby power loss, and features a low
component count.
